How do I interface to control the 6300

I have a Magloop controller that I need to interface to my Flex6300, the controller reads the Freq. of the radio, change to FM/AM, reduce the power and TX to get the best SWR. After the antenna is tune, the controller will restore the setting of the radio. The cable from the controller is a 3.5mm, 3 section stereo cable that works well with my Elecraft KX3. I need to build a similar cable to interface to my 6300, is this possible without adding any other external devices, and what pins on the DB15 connector do I use?

While I am not familiar with the Magloop controller, currently the 6000 series does NOT send band data directly from the Radio. Since it uses a 3.5mm TRS Connector I suspect that it is using some sort of Serial CAT data for Band Data.

However it is very easy to get band data from your computer that controls the radio. I suggest that you use a program like DDUTIL to act as a Traffic Cop to send data to the appropriate serial port.

To amplify my response. you can get whatever serial band data you need from your COMPUTER not directly from the Radio but rather indirectly through DDUTIL which reads the internal frequency data and converts it into serial data that your device can use.

"Tim - Is this something that will be implemented via software upgrades in the future ?"

We have discussed it internally and it may be part of an effort to fully remote the radio without having a PC at the remote site, but they are only preliminary discussions. DDUtil is the way to go for now.

I really hope Flex is able to do this Tim, as my remote site is Solar powered and it would certainly help the power budget and simplify the installation if I can control my amplifier without having to run a remote PC. I am sure there are many other Flex 6xxx users (and potential future Flex users) who would be in the same situation.
